Can Braces Fix Underbite?

September 28, 2024

If you're struggling with an underbite, you're probably wondering, "Can braces fix underbite?" An underbite can affect both the function of your teeth and the appearance of your jaw, causing discomfort and concerns about your smile. Many people turn to braces as a solution, but is it really the right choice for this issue? Whether you've had an underbite since childhood or it's developed later in life, understanding if braces can help is crucial. 

Let's find out if braces can fix your underbite and enhance your smile.

What Is An Underbite?

An underbite occurs when your lower teeth extend beyond the upper teeth when the mouth is closed, causing a misalignment of the jaw. This condition, also known as Class III malocclusion, creates a noticeable shift in how the teeth meet and can impact dental function and facial appearance.

What Causes An Underbite?

Genetics 

Family history often plays a significant role in the development of an underbite. If one or both parents have an underbite, there's a higher chance the child will develop it as well due to inherited jaw structure.

Childhood Habits

Prolonged thumb-sucking, bottle-feeding, or use of pacifier beyond infancy affects the alignment of the teeth and jaw and thus contributes to an underbite.

Tongue Thrusting

When the tongue pushes against the lower teeth during swallowing or speaking, the lower jaw can move forward, leading to an underbite.

Jawbone Development Issues

Uneven or improper growth of the upper or lower jaw during childhood can result in a misaligned bite, where the lower jaw becomes more prominent.

Injury or Trauma

Severe injury to the jaw or face can shift the alignment of the jaw, resulting in an underbite, especially if it heals improperly.

How Can Braces Fix Underbite?

Braces put gentle pressure to the teeth and shift them into the correct position. The treatment focuses on moving the lower teeth back or the upper teeth forward, depending on the severity of the condition. After some time, this realignment corrects the bite, and improves the function and appearance of your teeth.

The Process of Applying Braces For Underbite Correction

  1. Initial Assessment: The orthodontist first conducts a thorough evaluation, including X-rays and dental impressions, to determine the extent of the underbite.
  2. Brackets and Wires: Small brackets are then attached to each tooth, connected by wires. These wires apply the necessary force to move the teeth.
  3. Adjustments: Every few weeks, the orthodontist tightens or adjusts the wires and continues to guide the teeth into proper alignment. In some cases, elastics (rubber bands) may be used to help correct the bite.
  4. Retention Phase: After your braces are removed, a retainer must be worn to maintain the results and prevent the teeth from shifting back.

The movement happens in small increments, and adjustments are made regularly by an orthodontist to ensure the teeth are progressing toward the ideal alignment. This process can take anywhere from several months to a couple of years, depending on the complexity of the case.

Can Braces Fix Severe Underbite?

You must be wondering, Are Braces Effective for Severe Underbites? Braces are effective for mild to moderate underbites. In these cases, braces move the teeth into the correct position, fix the alignment, and improve the bite over time.

Sometimes, braces alone can provide a successful solution for most people with mild or moderate underbites. When it comes to severe underbites, braces alone may not be enough. Severe cases often involve not just the teeth but also the jawbone itself. In such cases, jaw surgery and braces may be required. The surgery helps to reposition the jaw, while braces are used to move the teeth into proper alignment afterward.

Can Braces Fix Underbite in Adults?

Braces can fix an underbite in adults, but the treatment might take longer and may require additional procedures. Since an adult's jaw is fully developed, fixing the alignment might be more challenging than for children or teens.

For adults, treatment may differ in these ways:

  • Longer Treatment Time: Since adult bones are no longer growing, it can take more time for braces to shift the teeth.
  • Surgery: In severe underbite cases, jaw surgery might be needed alongside braces to properly correct the bite. This surgery repositions the jawbone before braces are used to align the teeth.
  • Other Devices: Some adults may need additional orthodontic devices like elastics or expanders to assist braces in fixing the underbite.

Other Benefits of Correcting Underbite with Braces

Correcting an underbite with braces offers several health and aesthetic benefits beyond just straightening teeth.

  1. Improved Jaw Alignment: Braces help align the upper and lower jaws properly and reduce strain on the jaw muscles and joints. This can help prevent problems like TMJ disorders and jaw pain and make everyday activities like chewing and speaking more comfortable.
  2. Better Bite Functionality: A corrected underbite improves the way your teeth come together, making biting and chewing food easier and more efficient. This also helps protect your teeth from excessive wear and tear over time.
  3. Enhanced Facial Appearance: Fixing an underbite can improve facial symmetry and balance. When the lower jaw is no longer forward, the overall appearance of the face becomes better and boosts a person's self-confidence.
